NON-DOM: Remove the node object
NOTE: Specifically removes THIS NODE -- not the node with this
name, nor the node with these contents. If node does not belong to
this named node map, we throw a DOMException.

public Node removeNamedItem(String name)
throws DOMException {
return internalRemoveNamedItem(name, true);
}
/**
Same as removeNamedItem except that it simply returns null if the
specified name is not found.
